Study Notes
Soft Tissue Injuries Overview
- Superficial burn: Redness and pain, impacting only the outer skin layer (epidermis).
- Contusion: Closed soft-tissue injury leading to swelling and discoloration.
- Hematoma: Caused by damage to large blood vessels, resulting in localized bleeding.
Burn Classification
- Partial-thickness burn: Affects the dermal layer of skin, beyond the epidermis.
- Full-thickness burn: Extends through all layers of skin, including tissues beneath.
- Circumferential partial-thickness burn: Serious condition, especially around the chest.
Traumatic Injuries
- Abdominal evisceration: Organs protrude through a wound, requiring urgent care.
- Avulsion: Complete separation of skin layers, creating flaps or detached portions.
- Crush syndrome: Results from prolonged compression of extremities, leading to systemic complications.
Skin Functions
- Epidermis: Provides a watertight, protective seal for the body.
- Skin roles: Includes regulation of temperature, sensation relay to the brain, and water balance.
- Skin does not produce antibodies; this is a function of the immune system.
Injury Management
- Dressings: Essential for preventing contamination and controlling hemorrhage. They do not immobilize injuries.
- Open injuries: Expose deeper tissues and are at high risk for infection and complications.
- Proper care for chemical exposure: Brush off chemicals before washing with water.
Complications and Risks
- Infection: Significant risk associated with open soft-tissue injuries.
- Air embolism: Serious complication from open neck injuries, can be life-threatening.
Special Considerations
- Human bites: Can introduce various pathogenic bacteria, posing a higher infection risk.
- Assessment of closed injuries: Focus on potential underlying damage rather than skin integrity.
- Monitor for complications during treatment, such as possible loss of circulation.
Rule of Nines
- A system for estimating burn areas: The anterior trunk in adults equals 18% surface area; a child’s head equals 14%.
Types of Injuries
- Closed injuries: Damage beneath the skin without breaking its surface.
- Open injuries: Breaks in the skin expose deeper tissues to contamination.
- Incision: A clean, sharp cut resulting from a slicing force.
- Abrasion: Scraping of the skin, removing superficial layers.
Important Conditions
- Excited delirium: A behavioral condition with agitation, disorientation, and potential hallucinations.
- Risks associated with bandaging: Tight bandages may impede circulation; readjust if symptoms occur.
These notes cover essential terms, classifications, and considerations for soft tissue injuries, providing a comprehensive guide for studying the topic.
